Protection elevator used in case of earthquake

Abstract

The invention relates to the technical field of elevators, in particular to a protection elevator used in case of an earthquake. The protection elevator used in case of the earthquake comprises an elevator shaft, wherein a supporting frame is arranged on the elevator shaft; and a traction unit, a controller, and an earthquake detection device are arranged on the supporting frame, wherein the controller is used for controlling operation of the elevator, the earthquake detection device is used for sensing earthquake risk signals, an output shaft of the traction unit is connected with a tractionwheel, a traction rope is arranged on the traction wheel, one end of the traction rope is connected with a lift car, the other end of the traction rope is connected with a balancing weight, gear guiderails are uniformly arranged on the parts, on the two sides of the lift car, of the inner wall of the elevator shaft from bottom to top, emergency landing devices matched with the gear guide rails are arranged on the two sides of the top of the lift car correspondingly, and an anti-vibration layer is arranged at the bottom of the lift car. According to the protection elevator, the earthquake canbe sensed in advance, the elevator stops running after running to a safe evacuation floor in time, and thus the safety of personnel and equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an earthquake-proof elevator. Background technique [0002] With the progress of society, the vigorous development of industry and construction industry, there are more and more high-rise buildings, so elevator equipment has been widely used accordingly, and with the increase in the number of high-rise buildings and the increase in height, the requirements for elevator applications have also increased accordingly, especially for Safety considerations are insufficient, and when a safety emergency occurs, the lives of passengers are threatened. [0003] my country is an earthquake-prone country. Since the 20th century, there have been nearly 800 earthquakes of magnitude 6 or above. As a big country in elevator production and consumption, China has 70% elevators installed in earthquake zones. When an earthquake occurs, the earthquake will cause great damage to equipment such as ...
